Advanced Port Air Quality Monitoring for Port of Cotonou

Port of Cotonou

The Port of Cotonou faced significant environmental challenges, from harsh coastal climates to unidentified pollution sources threatening public health. By implementing a science-driven IAQ Audit and a network of 17 smart monitoring stations, Airscan provided the data-driven clarity needed to safeguard the maritime gateway. This partnership transformed environmental uncertainty into actionable insights, establishing the port as a regional leader in sustainability and livability.

PortuAIR is redefining environmental standards in the maritime sector through an innovative, connected approach to air quality monitoring. By leveraging smart sensors and real-time data analysis, the project provides a comprehensive understanding of how port activities impact both the environment and public health. This initiative ensures that the Port of Cotonou, a vital hub for international trade, can grow its capacity while maintaining a strict commitment to livability.

The Challenge: Monitoring the Invisible in Harsh Conditions

The Autonomous Port of Cotonou operates within a complex 79 km² area, facing unique environmental stressors that previously hindered accurate data collection.

  • Environmental Resilience: The region’s harsh climatic conditions posed a constant threat to the reliability of standard monitoring equipment.
  • Pollution Source Identification: With diverse port activities, pinpointing the specific contributors to pollution peaks was historically difficult.
  • Local Technical Independence: There was a critical need to transfer technical expertise to port engineers to ensure long-term, independent management of environmental data.

The Solution: A Science-Based IAQ Infrastructure

Airscan, in partnership with Enabel and Eco-Bénin, deployed a robust Environmental Quality framework designed for durability and precision.

Comprehensive Sensor Network

We installed 17 monitoring stations to track key pollutants, including PM1, PM2.5, PM10, NO₂, and SO₂. Additionally, seven specialized rain gauges were deployed to assess the atmospheric deposition of heavy metals and PAHs, providing a 360-degree view of environmental health.

Integrated Data Platform

All data is centralized in a digital platform that combines real-time pollution metrics with meteorological and operational insights. This allows port authorities to make informed, science-driven decisions regarding policy and daily operations.

Capacity Building

Airscan conducted intensive workshops for port engineers, focusing on data analysis and system maintenance. This ensures the project remains sustainable and led by local expertise.

The Result: Leadership in Sustainability

The implementation of the PortuAIR system has shifted the port from reactive management to proactive stewardship.

  • Improved Awareness: Management and stakeholders now have a transparent view of air quality levels, fostering engagement with environmental issues.
  • Evidence-Based Policy: Real-time data has directly informed new port policies, leading to measurable improvements in local air quality.
  • Regional Influence: The Port of Cotonou is now recognized as a pioneering model of environmental responsibility in the West African maritime sector.
